For more information about using scan-build for the static
analyser, look at http://clang-analyzer.llvm.org/scan-build.html

For instance, the scanner on the kernel build can be launched with:

cd /usr/src/sys/arch/`uname -m`/conf && config GENERIC.MP
cd /usr/src/sys/arch/`uname -m`/compile/GENERIC.MP
make clean && scan-build make

This will generate HTML reports in /tmp/scan-build-(date).
